The purpose of this utility model provides a kind of energy-efficient pendulum type ring roll pulverizer group, and its production efficiency and fractional energy savings will improve more than 20% than existing unit.
The purpose of this utility model is by cancelling the analytical engine in the former unit, and the high performance centrifugal separator of the band filter screen that uses with 3 series connection substitutes, and existing old-fashioned separator realizes.
The utility model has been cancelled the analytical engine in the former unit, and with the whizzer of a band filter screen larger particles ore separation that finished product requires that do not reach that blower fan blows afloat is gone out, and concentrate to send again in former pendulum type ring roll pulverizer or the newly-increased flour mill and grind once more, so not only capable of reducing energy consumption, and can improve unit output, separate respectively and further will reach rough powder and the mineral fine that finished product requires with the whizzer of two band filter screens.Then not only separative efficiency is more much higher than old-fashioned separator, makes in the wind net air contain the ore deposit deal and reduces significantly, and made essential condition for reelecting the efficient centrifugal blower fan shape that efficient reaches about 80%.
The utility model compares with existing unit that to have a project organization scientific and reasonable, select for use device structure simply suitable, output is big, efficient height, power consumptive province, use easy to maintenance, long service life, widely applicable, and product can divide the thickness powder, the product quality advantages of higher, the equal highly significant of its economic and social benefit.
Be described further below in conjunction with drawings and Examples.
Accompanying drawing is the utility model general structure schematic diagram.Among the figure: 1 pipeline, 2 mineral fine separators, 3 rough powder separators, 4 bulky grain ore separators, 5 bucket elevators, 6 material choosing apparatus, 7 bulky grain ore storage bunkers, 8 centrifugal blowers, 9 jaw crushers, 10 pendulum type ring roll pulverizers.
As shown in the figure, the jaw crusher (9) that the utility model adopts, bucket elevator (5) and pendulum type ring roll pulverizer (10) are installed on the same floor level, jaw crusher outlet (9) is facing to the material hole of bucket elevator (5) bottom, bucket elevator (5) upper part discharge port links to each other with material choosing apparatus (6) import of pipeline with its below, the outlet of material choosing apparatus (6) is the charging aperture of straight-through pendulum type ring roll pulverizer (10) then, the outlet of pendulum type ring roll pulverizer (10) upper end links to each other with the import of bulky grain ore separator (4), below contact successively more rough powder separator (3) and mineral fine separator (2), the air outlet of the upper end of mineral fine separator communicates with the air inlet of centrifugal blower, the air outlet of centrifugal blower then links to each other with the air inlet of pendulum type ring roll pulverizer bottom, in addition, bulky grain ore separator lower end powder outlet communicates with the bulky grain ore storage bunker, and thick, the powder outlet of pulverized-coal collector lower end then respectively with slightly, fine powder feed bin (not drawing among the figure) communicates.The technological process of the utility model powder ore is: ore be introduced into jaw crusher (9) be extruded be broken into fritter after, mention with bucket elevator (5), pass through again and enter pendulum type ring roll pulverizer (10) behind the material choosing apparatus (6) and further ground, in pendulum type ring roll pulverizer (10), be ground into after the Powdered finished product that reaches the finished product requirement and a part do not reach air that ore particles that finished product requires granularity blown out by centrifugal blower (8) and upwards blow afloat from pendulum type ring roll pulverizer (10) bottom, directly enter bulky grain ore separator (4), the filter screen aperture of bulky grain ore separator (4) is selected by the maximum particle diameter requirement that the ore particles that can pass filter screen just can reach the finished product meal.After can passing filter screen, the mineral powder that reaches the finished product requirement like this enters rough powder separator (3) again.The bulky grain ore that does not reach the finished product granularity requirements then is blocked in outside the filter screen, and falls into the bulky grain ore storage bunker by the separator lower end powder outlet.Rough powder separator (3) the filter screen aperture proportionately maximum particle diameter of product fine powder requires to select, the mineral fine that reaches the requirement of finished product fine powder like this can pass filter screen and enter mineral fine separator (2) again, rough powder then is blocked in outside the filter screen, after discharging, the separator lower end powder outlet promptly enters rough powder storehouse (not drawing the figure), in like manner mineral fine separator (2) is separable goes out mineral fine, mineral fine is discharged from mineral fine separator (2) lower end powder outlet, and enters mineral fine storehouse (not drawing among the figure).From the air that mineral fine separator (2) upper end air outlet is discharged, just only contained the minute quantity super finely ground slag (can also increase primary separator, separating ultra-fine powder more if desired) like this.Basic clean air enters centrifugal blower (8) by pipeline (1) again and begins next circulation again.Above technological process is the disintegrating process flow process that pneumatic classification separates.The purpose that increases a bulky grain ore storage bunker in this unit is that the bulky grain ore is stored, wait to accumulate a certain amount of, cut off the supplied materials of material choosing apparatus (6) after, the bulky grain ore directly sent in the pendulum type ring roll pulverizer (10) grinds separately.Can avoid entering grinding machine like this and influence grinding effect with lump ore.In addition also can be without the bulky grain ore storage bunker, grind and the bulky grain ore directly sent in small dimension pendulum type ring roll pulverizer increasing in addition or the percussion grinder.Can increase considerably unit output like this.
